You'll save major counter space if you get rid of it, too.​

Anthony Bourdain isn't known for beating around the bush. The 59-year-old star of travel food shows, like No Reservations and Parts Unknown, is famous for telling it like it is and being firm in his beliefs. So when we heard he thinks we're all wasting money on something in our kitchens, we needed to know more.

According to Bourdain, we should all stop buying knife sets. In his 2000 memoir, Kitchen Confidential, he says medium-size utility knives advertised on TV are "hard to sharpen" and "ineptly designed." We'll also add that they tend to be quite expensive. His solution? "Please believe me, here's all you will ever need in the knife department: One good chefs knife, as large as is comfortable for your hand."

But which one should you buy? Instead of investing in an expensive Henkel or Wusthof knife that requires maintenance that's not realistic for an amateur chef, he recommends opting for a lightweight and inexpensive vanadium steel Global design. Then, to use this tool for all of your slicing needs, he says to use the tip for small stuff and the area near the heel for larger stuff.

The only downside: Purging your knife collection means you won't be able to enlist as many sous chefs to help you tackle chopping for your vegetable tray the next time you entertain. Maybe this is a case for holding onto a few smaller blades, just to be safe.
